Hi,
I recently acquired a 1957, 445, Minneapolis Moline. It had been sitting for many years in the dirt outside. Here is my progress so far. After a soak in oil, I was able to get the engine to turn over and now running. It smokes pretty significantly. I replaced all the tires to get it rolling again. All the gears work as well as the Ampli-torque. I am waiting for axle seals to get enough oil in it completely diagnose the hydraulics. Here is the question. The engine is worn beyond specs in several area. [b:82115cc0e9]How do you decide how far to go in a rebuild?[/b:82115cc0e9]
A few more details: I replaced the water pump. I replaced the valve guides and reground all the valves and seats (easier attempt to reduce the oil burning) One valve was badly cracked. The oil burning was even worse, so I dug deeper. I found the compression rings have about a .09" end gap, and the oil rings have about a .18" end gap (worn out) Also, the main and rod bearings are worn partially into the copper lining. The crank end play is about .08" The decision is to decide how far to go to return it to light duty use for shows/parades. Any advise is much appreciated. Thank you.
